This is a set of 24 QR code task cards aligned to the first grade common core standards:
Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
Students will need to identify measurement mistakes, order three objects by length, measure objects, and determine how much longer one object is.
QR codes are included so that students can check their work.
*Update: 2 versions of the task cards are now included: one with QR codes, and one without
Ideas for using task cards in your classroom:
-write the room
-early finisher choice
-cooperative learning activity
